We study Shatalov-Sternin's proof of existence of resurgent solutions of a linear ODE and discuss the construction of analytic continuation to a common ``Riemann surface'' of all terms of the von Neumann series appearing in their proof. We give a detailed proof of a more modest statement in a special situation.
